Description
456 0869 . _ I Indikering av innehållet i en kassett bygger pa principen att lata dryckes- förpackningarna ingå i en kondensators dielektrikum, varvid kondensatorns kapacitans blir beroende av antalet förpackningar i kassetten. I fig.4 visas schematiskt tre förpackningar llia, b, c inlagda i kassetten 13 som har en övre vägg 15 och en undre vägg 16. De bada väggarna är på utsidan klädda med tunna metallskikt 17, 18 vilka är sammankopplade medelst en ledare 19. Metallskikten är anslutna till jordpotential och bildar en skärm som elektriskt separerar de olika kassetterna fràn varandra. De tre *förpackningarna vilar med ett mellanliggande tunt skikt av isolerande material pà remsor 20a, b, c av elektriskt ledande material. Dessa samverkar med pa insidan av väggen 15 anordnade remsor 2la, b, c, för att med dessa bilda tre kondensatorer 22a, b, c, fig. 5, vilka är parallellkopplade med varandra. Som kan ses i fig. 4 är remsor- na 20a, b, c sammankopplade medelst ledare 23 och remsorna 2la, b, c med ledare 24. 456 0869. I Indication of the contents of a cassette is based on the principle that the beverage packages are included in a capacitor's dielectric, whereby the capacitor's capacitance depends on the number of packages in the cassette. Fig. 4 schematically shows three packages 11a, b, c inserted in the cassette 13 which have an upper wall 15 and a lower wall 16. The two walls are clad on the outside with thin metal layers 17, 18 which are connected by means of a conductor 19. The metal layers are connected to ground potential and form a screen that electrically separates the different cassettes from each other. The three packages rest with an intermediate thin layer of insulating material on strips 20a, b, c of electrically conductive material. These co-operate with strips 2la, b, c arranged on the inside of the wall 15 to form with them three capacitors 22a, b, c, Fig. 5, which are connected in parallel with each other. As can be seen in Fig. 4, the strips 20a, b, c are connected by means of conductors 23 and the strips 2la, b, c with conductors 24.
För anslutning av kassetten till en mätanordning är remsan 2lc medelst en ledare 25 förbunden med en terminal 26 och pà motsvarande sätt remsan 20c vie en ledare 27 förbunden med en terminal 28. Kapacitansen mellan terminalen 26 och jord anges i fig. 5 under beteckningen 29 medan kapacitansen mellan terminalen 28 och jord betecknas 30. I det visade exemplet har av skäl som kommer att framgå nedan de ledande omradena bildats av smala remsor i anslutning till varje lagringsposition.To connect the cassette to a measuring device, the strip 21c is connected by means of a conductor 25 to a terminal 26 and correspondingly the strip 20c to a conductor 27 is connected to a terminal 28. The capacitance between the terminal 26 and ground is indicated in Fig. 5 under the designation 29 while the capacitance between the terminal 28 and ground is denoted 30. In the example shown, for reasons which will appear below, the conductive areas have been formed by narrow strips adjacent to each storage position.
Alternativt kan dock remsorna ersättas av ledande områden som i form av ett metallskikt, en metallplatta eller dylikt sträcker sig över alla lagríngspositionerna. Det tunna skiktet av isolerande material ges därvid samma utformning.Alternatively, however, the strips may be replaced by conductive areas which in the form of a metal layer, a metal plate or the like extend over all the storage positions. The thin layer of insulating material is then given the same design.
I det följande skall nagra exempel ges på praktiska beräkningar av kapacitansen hos kondensatorerna 22a, b, c vilka sammantagna bildar kapacitansen Ck. I kassetten kan vissa mattstorheter inte pâverkas och till dessa hör avståndetd mellan konden- satorns plattor, liksom plattornas bredd = burkens längd + ett visst glapp. Kassettens längdl beror av antalet förpackningar och är i exemplet lika med 'šganger burkens diameter. I burkfallet är d = æ 0,072 m, b = 0,ll m och l = 0,2 m. Traditionell kapaci- tansberäkning ger för den tomma kassetten värdet 2,7* pF.In the following, some examples will be given of practical calculations of the capacitance of the capacitors 22a, b, c which together form the capacitance Ck. In the cassette, certain mat sizes cannot be affected and these include the distance between the capacitor plates, as well as the width of the plates = the length of the can + a certain play. The length of the cassette depends on the number of packages and in the example is equal to the diameter of the can. In the can case, d = æ is 0.072 m, b = 0, 11 m and l = 0.2 m. Traditional capacitance calculation gives the value for the empty cassette 2.7 * pF.
När en ledande cylinder (burken) läggas mellan plattorna ökas kondensatorns kapacitans. Ökningen beror av cylinderns diameter och placering mellan plattorna.When a conductive cylinder (can) is placed between the plates, the capacitance of the capacitor increases. The increase depends on the diameter of the cylinder and the location between the plates.
Symmetrisk placering ger lägst ökning av kapacitansen medan den största ökningen erhålles med burken vilande mot den ena kondensatorplattan under mellanlägg av en tunn isolerande tejp med tjockleken 0,05 mm. Den ökning som erhålles med den visade placeringen av burken uppgår till 4,5 pF.Symmetrical placement gives the lowest increase in capacitance while the largest increase is obtained with the can resting against one capacitor plate under the interposition of a thin insulating tape with a thickness of 0.05 mm. The increase obtained with the shown placement of the can amounts to 4.5 pF.
En kassett för flaskor har större bredd b = 0,22 m. Övriga mätt är desamma. En tom kassett får kapacitansen 5,329 pF (beräknat värde). Flaskans innehåll betraktas som ledande vilket är en fullt acceptabel approxímation. Flaskans innerdiameter är mindre än burkens yttre diameter, varför kapacitansökningen blir mindre. Med flaskan placerad som i burkfallet 0,05 mm från nedre plattan blir den maximala ökningen ca. 3,5 pF. 456 869 Speciellt vid flaskor kan förekomsten av etiketter förvränga mätresultatet. Kapaci- tansen mellan plattorna far nämligen olika värden beroende pa om etiketten är vänd nedat eller at nagot annat hall. För att minska etikettens inverkan bör den isolerande tejpens tjocklek vara åtminstone lika stor som tjockleken pa etiketten.A cassette for bottles has a larger width b = 0.22 m. Other measurements are the same. An empty cassette has a capacitance of 5,329 pF (calculated value). The contents of the bottle are considered conductive, which is a fully acceptable approximation. The inner diameter of the bottle is smaller than the outer diameter of the can, so the capacity application becomes smaller. With the bottle placed as in the can case 0.05 mm from the lower plate, the maximum increase will be approx. 3.5 pF. 456 869 Especially with bottles, the presence of labels can distort the measurement result. The capacity between the tiles has different values depending on whether the label is turned down or in another hall. To reduce the effect of the label, the thickness of the insulating tape should be at least equal to the thickness of the label.
I anslutning till de praktiska beräkningarna har antagits att kondensator-plattorna sträcker sig utefter hela ytan av väggarna 15, 16 i fig. ll. Det är dock fördelaktigt att istället utföra kondensatorplattorna som remsor vilka placerats pa väggarna 15 respektive 16 endast i anslutning till de positioner i facket där burkar eller flaskor kan befinna sig. Kapacitansökningarna blir desamma men kapacitansen för den tomma kassetten blir lägre, i burkfallet 0,8 pF och för flaskkassetten 1,6 pF. Förutom minsk- ningen i kassettens tomkapacitans ger den beskrivna utformningen av kondensator- plattorna ett lägre värde pa kapacitansen 30. Fördelen härmed kommer att anges i det följande.In connection with the practical calculations it has been assumed that the capacitor plates extend along the entire surface of the walls 15, 16 in Fig. 11. However, it is advantageous to instead make the capacitor plates as strips which are placed on the walls 15 and 16, respectively, only in connection with the positions in the compartment where cans or bottles can be located. The capacity applications will be the same, but the capacitance for the empty cassette will be lower, in the can case 0.8 pF and for the bottle cassette 1.6 pF. In addition to the reduction in the empty capacitance of the cassette, the described design of the capacitor plates gives a lower value of the capacitance 30. The advantage of this will be stated in the following.
Mätning av kapacitansen Ck i kassetten sker enligt uppfinningen genom att en lagfrekvent sinusspänning Uin paföres terminalen 26 och ger upphov till en utspänning Uut pa terminalen 28, vars amplitud beror av antalet burkar eller flaskor i kassetten.Measurement of the capacitance Ck in the cassette takes place according to the invention in that a law-frequency sine voltage Uin is applied to the terminal 26 and gives rise to an output voltage Uin on the terminal 28, the amplitude of which depends on the number of cans or bottles in the cassette.
Utspänningen dämpas kraftigt av ett högpassfilter som bildas av kapacitansen Ck och en resistans R. Detta medför att redan sma ändringar i kapacitansen Ck resulterar i stora ändringar i dess impedans. Resistansvärdet väljes sa att utsignalen blir sa stor som möjligt. Detta uppnås om R väljes stor samtidigt som kapacitansen 30 är liten. För att undanröja inverkan av variationer i kapacitansen 30 pa grund av konstruktiva ofull- komligheter väljes dock ett högre värde pa denna kapacitans än det optimalt lägsta med atföljande minskning av utspänningen. För en kassett med burkar har följande värden pa utspänningen uppmätta: tom kassett - 0,10 volt, en burk - 0,27 volt, tva burkar - 0,43 volt och tre burkar - 0,56 volt. Motsvarande värden för en flaskkassett har uppmätts till 0,09 volt, 0,17 volt, 0,26 volt respektive 0,32 volt. l fig. 6 återges ett blockschema över en anordning 31 för mätning av ett antal kassetter 13, i exemplet sex stycken. Mätanordningen genererar analoga mätvärden i form av likspänningar vilka i ett datorbaserat system omvandlas till digital form. Detta faller dock utanför uppfinningens ram och kommer inte att beskrivas närmare. Den i fig. 5 visade mätkretsen kan kopplas till mätanordningen pa nagot känt sätt. I det i fig. 1 - 3 visade utförandet är kassetten vid sin baksida utförd med tva metall- plattor 32, 33, vilka samverkar med tva i varje fack anordnade plattor 34, 35. Plattan 32 motsvarar terminalen 26 i fig. 4 medan plattan 33 motsvarar terminalen 28. Via plattorna 34, 35 kopplas den inskjutna kassetten kapacitivt till mätanordningen 3l.'l kretsschemat i fig. 3 representeras plattorna 32, 34; 33, 35 av kondensatorer 36, 37.The output voltage is strongly attenuated by a high-pass filter formed by the capacitance Ck and a resistance R. This means that even small changes in the capacitance Ck result in large changes in its impedance. The resistance value is selected so that the output signal is as large as possible. This is achieved if R is selected large while the capacitance 30 is small. However, in order to eliminate the effect of variations in the capacitance due to constructive imperfections, a higher value of this capacitance is selected than the optimum lowest with the consequent reduction of the output voltage. For a cassette with cans, the following values of the output voltage have been measured: empty cassette - 0.10 volts, one can - 0.27 volts, two cans - 0.43 volts and three cans - 0.56 volts. The corresponding values for a bottle cassette have been measured at 0.09 volts, 0.17 volts, 0.26 volts and 0.32 volts, respectively. Fig. 6 shows a block diagram of a device 31 for measuring a number of cassettes 13, in the example six pieces. The measuring device generates analogue measured values in the form of direct voltages which in a computer-based system are converted into digital form. However, this falls outside the scope of the invention and will not be described in more detail. The measuring circuit shown in Fig. 5 can be connected to the measuring device in a known manner. In the embodiment shown in Figs. 1-3, the cassette is made at its rear side with two metal plates 32, 33, which cooperate with two plates 34, 35 arranged in each compartment. The plate 32 corresponds to the terminal 26 in Fig. 4 while the plate 33 corresponds to the terminal 28. Via the plates 34, 35 the inserted cassette is capacitively connected to the measuring device 31 in the circuit diagram in Fig. 3, the plates 32, 34 are represented; 33, 35 of capacitors 36, 37.
Dessa väljes stora för att ej paverka mätningen.These are chosen large so as not to affect the measurement.
Inspänningen till mätkretsen i fig. 5 genereras av en funktionsgenerator 38' som avger en sinusspänning. Efter förstärkning i en förstärkare 39 ledes signalen till en av 456 869 kassetterna 13 via en multiplexer 40. Denna styres av styrsignaler pà en databuss 41 så att den inkopplar de sex kassetterna i följd till mätanordningen. Från förstärkaren 39 ledes signalen även till en dämpanordning 42 för flaskkassetter respektive en dämp- anordning 43 för burkkassetter. Signalen från den inkopplade kassetten ledes via en multiplexer 44 och en impedansomvandlare 45 till plusingängen på en differential- förstärkare 46. Minusingången på denna är via en rnultiplexer 47 ansluten till ut- gängarna på dämpanordningarna 42, 43. Utgângen pà differentialförstärkaren är via en multiplexer 48 och en ytterligare multiplexer 49 ansluten till en likriktare 50 via en förstärkare 51 och en impedansomvandlare 52. Likriktaren är ansluten till en A/D-omvandlare 53 som omvandlar de analoga spänningsvärdena till digital form för att överföras till en icke visad dator via en databuss 54. En ledare 55 förbinder direkt de båda multiplexerenheterna 48 och 49. Dessa är även förbundna via en förstärkare 56. Då signalerna från en flaskkassett har lägre nivå än de från en burkkassett måste förstärkning tillgripas om samma mâtkedja skall kunna användas. En flaskkassettsignal ledes därför via förstärkaren 56 medan en burkkassettsignal ledes via ledaren 55.The input voltage to the measuring circuit in Fig. 5 is generated by a function generator 38 'which emits a sine voltage. After amplification in an amplifier 39, the signal is passed to one of the 456 869 cassettes 13 via a multiplexer 40. This is controlled by control signals on a data bus 41 so that it connects the six cassettes in succession to the measuring device. From the amplifier 39 the signal is also routed to a damping device 42 for bottle cassettes and a damping device 43 for can cassettes, respectively. The signal from the connected cassette is fed via a multiplexer 44 and an impedance converter 45 to the plus input of a differential amplifier 46. The negative input of this is connected via a multiplexer 47 to the outputs of the attenuators 42, 43. The output of the differential amplifier is via a multiplexer 48 and a further multiplexer 49 connected to a rectifier 50 via an amplifier 51 and an impedance converter 52. The rectifier is connected to an A / D converter 53 which converts the analog voltage values into digital form for transmission to a computer (not shown) via a data bus 54 A conductor 55 directly connects the two multiplexer units 48 and 49. These are also connected via an amplifier 56. Since the signals from a bottle cassette have a lower level than those from a can cassette, reinforcement must be used if the same measuring chain is to be used. Therefore, a bottle cassette signal is passed through the amplifier 56 while a can cassette signal is passed through the conductor 55.
De tvâ dämpanordningarna 42, 43 har till funktion att till differentialförstär- karen 46 avge en signal som med signalen från kassetten vid tom sådan ger ut- spänningenüvolt från förstärkaren och därmed en kalibrering av denna. De olika multiplexerenheterna 40, 44, 47, 48, 49 styres av styrsignaler pa bussen 41 för att i tur och ordning inkoppla de sex olika kassetterna 13 till mätanordningen. Därvid väljes även via styrsignalerna rätt dämpanordning 42 eller 43 liksom om förstärkaren 56 behöver inkopplas. f)The function of the two attenuation devices 42, 43 is to emit to the differential amplifier 46 a signal which, with the signal from the cassette at even such, gives the output voltage unvoltaged from the amplifier and thus a calibration thereof. The various multiplexer units 40, 44, 47, 48, 49 are controlled by control signals on the bus 41 to in turn connect the six different cassettes 13 to the measuring device. In this case, the correct attenuating device 42 or 43 is also selected via the control signals, as well as whether the amplifier 56 needs to be switched on. f)
